Abstract

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for updating QoS configurations at a user equipment (UE). An example method generally includes receiving, from a network entity, quality of service (QoS) information, a QoS identifier associated with the QoS information, and a bearer context associated with the QoS information in one of a modify bearer context request message, an activate default bearer context request message, or an activate dedicated bearer context request message; and updating a QoS configuration using the QoS information based on whether the UE is already configured with QoS information associated with the QoS identifier for a bearer context different from the bearer context associated with the QoS information received in the modify bearer context request message, activate default bearer context request message, or activate dedicated bearer context request message.
